If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
straight angle
An angle is formed by a point on the end and two rays
An angle formed by two planes is called a dihedral angle. It is the angle between two intersecting planes and is measured along a line of intersection. Dihedral angles are commonly encountered in geometry and three-dimensional shapes.
This is the definition of an inscribed angle in geometry. An inscribed angle is formed by two chords in a circle that also share a common point called the vertex.
An inscribed angle is formed by two chords in a circle that meet at a common endpoint on the circle's circumference. The vertex of the angle lies on the circle, and the sides of the angle are segments of the chords. The measure of an inscribed angle is half the measure of the arc that it intercepts. This property is a key characteristic of inscribed angles in circle geometry.
straight angle
This is known in geometry as an interior angle.
An angle is formed by a point on the end and two rays
In geometry, an interior angle is an angle formed by two sides of a simple polygon that share an endpoint, namely, the angle of the inner side of the polygon.
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

It is called an angle!
It means Angle, Angle, Angle.

It is the alternate angle to the angle of elevation
It is an angle that is 90 degrees.
